FASTENING OF THE SPRING-SOCKETS OF PRESS-BUTTONS.

Specification of Letters Patent.

Patented Dec. 6, 1921.

Application filed November 2-3, 1914. Serial No. 873,617.

(GRANTED UNDER THE PROVISIONS OF THE ACT OF MARCH 3, 1921, 41 STAT. L,1313.)

To (:ZZ to]: 0m it may concern Be it known that I, AUGUST PRYM,manufacturer, a citizen of the Empire of Germany, residing at Biisbach,near Stolberg, Villa lVa-ldfriede, in the Empire of Germany, haveinvented a new and useful Improvement in Fastenings of theSpring-Sockets of Press-Buttons, (for which I have filed an applicationin Germany Sept. 13, 1918,) of which the following is a specification.

The present invention relates to improvements in separable buttonsparticularly to spring pressed buttons comprising a socket member and acap.

It is the object of the present invention to provide a button, thesocket of which has a turned over edge underneath which the body of adouble shank wire spring is held, the hanks of which are guided throughin cisions in a perforated dome projecting from the center of the socketplate.

Another object of the invention is to provide a separable button thesocket member which and the cap can be united above a piece of fabric bya slight pressure by providing the dome at its top with an opening intowhich fits the outwardly flared nipple of the cap with an elastic snapas soon as a pressure is exerted upon socket and cap, providing a firmhold which yet may be overcome easily to separate the parts if this isthe intention.

In this manner a reliable fastening of the press but-ton part isobtained which may easily be carried out by special machines and whichis far superior to the customary sewing both as regards strength andrapidity of execution.

The manner in which the new fastening is effected may be seen in Figures1 to 5 of the accompanying drawing, in which:

Fig. 1 is a top plan view of the socket plate with the double shank wirespring.

Fig. 2 is a vertical cross-section through the parts shown in Fig. 1. i

Fig. 3 is top plan view of the cap.

4; is a section through the same, and

Fig. 5 is a vertical cross-section through the socket and cap combined.

In the figures, a represents the socket plate, in which a double shankwire spring 5 is arranged and rigidly held by the turned over edge ofthe plate (4. rom the middle of the plate, the dome (Z projects, whichhas incisions at e in which the two elastic shanks of the wire spring 6acting on the interior of the dome, can move freely. The top of the dome(Z is perforated at into this perforation the hollow'outwardly flarednipple 17b in the middle of the inner face of the cap is elasticallyfitted with a snap action.

In a separable button, the combination with a socket plate having aturnea over edge, a double shank wire spring rigidly held with its bodyunderneath of said turned over edge in said socket plate, a perforateddome projecting from the middle of the plate provided with incisions,permitting a free movement of the elastic shanks-of said wire springacting on the interior of the dome, a cap, a hollow rivet on said capand an outwardly flared flange on said rivet adapted to be inserted intothe perforation of said dome and to be turned down around the edge ofsaid perforation for tightly gripping the material between the cap andsocket plate, substantially as described.
